I don't know if it's by design. I have placed a single file at a fixed lcn with
SetBeginOfZone(AtCluster(100000))
FileSelect
FullName("K:\SomeFile.txt")
FileActions
SortByName(Ascending)
FileEnd
If I change the script and try to move the not fragmented file til cluster 50000 the file isn't moved.
The only way I can move the file is to use ForcedFill().
TIA
